Ok So I have an iPhone 3G on 4.2.1 that's unlocked with ultras 0w and it's pretty slow. My iPod 2g on 4.2.1 has the same amount of memory but the animations and processes are generally a Lot smoother. In addition, it appears that when I unlock my iPhone from the lockscreen, it lags the most when the wifi symbol isn't there for a few seconds then appears and then the lag lessens a little. Can someone please help me ???

My iPhone barely has any tweaks (if anything, my iPod has many more tweaks installed!)
